Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean is higher than 9.33, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Answer:
(0,50)
Step-by-step explanation:
Given the total cost of a dancers lesson modeled by the equation y = 25x + 50, the y intercept occurs at the point where x = 0.
Substitute x = 0 into the expression
y = 25x + 50
y = 25(0) + 50
y = 0+50
y = 50
Hence the y intercept is (0, 50). This shows that the total cost of the dancers lesson registration fee is 50
A polyhedron is formed by intersecting planes. That means that each part of its surface is a vertex, edge, or a flat piece of a plane.
17 . Find the values of g(9) and h(-14) and add them together.
The function equations are given to find their values substitute 9 in g(x) and -14 in h(x)
20. They said f(x) = 2x + 9 and f(x) = 15 , which means they are equal to each other.
So write them as 2x + 9 = 15 , and solve the equation to find the value of x.
25. Here all you have to do is substitute 4 into the f(x) equation to find f(4)and you will have your answer.
Hope this helped!
Y = |x - 3|You need an equation so that you need to add 3 to get the same value. Changing from 'x' to 'x - 3' requires a value (of the second expression) that is 3 larger than the entry in the first expression.
